I have three Hyper-V Servers all on one physical machine,
1. Domain Controller 1 running WIndows 2012
2. Domain Controller 2 Running Windows 2012
3. Exchange 2010 running Windows 2008 R2
after a few months running just fine, suddenly the Exchange server is complaining it cannot find the DC's.
I get the Application Error logs saying Event ID 2604 MSExchangeADAccess
Eventi ID 2103, 2114, and 2102.
I already looked at the Default Domain Security settings where you make sure it is the Local Domain Controllers policy and not just the Local Domain policy.
Then I reboot and it seems fine...for awhile. Any ideas?
